ABSTRACT

Tricyclic compounds of the general Formula I: ##STR1## as defined herein which exhibit antagonist activity at V 1  and/or V 2  receptors and exhibit in vivo vasopressin antagonist activity, methods for using such compounds in treating diseases characterized by excess renal reabsorption of water, and processes for preparing such compounds.

This is a continuation-in-part of application Ser. No. 08/100,003 filed on Jul. 29, 1993, now abandoned.

FIELD OF THE INVENTION

This invention relates to new tricyclic non-peptide vasopressin antagonists which are useful in treating conditions where decreased vasopressin levels are desired, such as in congestive heart failure, in disease conditions with excess renal water reabsorption and in conditions with increased vascular resistance and coronary vasoconstriction.

BACKGROUND OF THE INVENTION

Vasopressin is released from the posterior pituitary either in response to increased plasma osmolarity detected by brain osmoreceptors or decreased blood volume and blood pressure sensed by low-pressure volume receptors and arterial baroreceptors. The hormone exerts its actions through two well defined receptor subtypes: vascular V₁ and renal epithelial V₂ receptors. Vasopressin-induced antidiuresis, mediated by renal epithelial V₂ receptors, helps to maintain normal plasma osmolarity, blood volume and blood pressure.

Vasopressin is involved in some cases of congestive heart failure where peripheral resistance is increased. V₁ antagonists may decrease systemic vascular resistance, increase cardiac output and prevent vasopressin induced coronary vasoconstriction. Thus, in conditions with vasopressin induced increases in total peripheral resistance and altered local blood flow, V₁ -antagonists may be therapeutic agents. V₁ antagonists may decrease blood pressure, induce hypotensive effects and thus be therapeutically useful in treatment of some types of hypertension.

The blockade of V₂ receptors is useful in treating diseases characterized by excess renal reabsorption of free water. Antidiuresis is regulated by the hypothalamic release of vasopressin (anti-diuretic hormone) which binds to specific receptors on renal collecting tubule cells. This binding stimulates adenylyl cyclase and promotes the cAMP-mediated incorporation of water pores into the luminal surface of these cells. V₂ antagonists may correct the fluid retention in congestive heart failure, liver cirrhosis, nephrotic syndrome, central nervous system injuries, lung disease and hyponatremia.

Elevated vasopressin levels occur in congestive heart failure which is more common in older patients with chronic heart failure. In patients with hyponatremic congestive heart failure and elevated vasopressin levels, a V₂ antagonist may be beneficial in promoting free water excretion by antagonizing the action of antiduretic hormone. On the basis of biochemical and pharmacological effects of the hormone, antagonists of vasopressin are expected to be therapeutically useful in the treatment and/or prevention of hypertension, cardiac insufficiency, coronary vasospasm, cardiac ischemia, renal vasospasm, liver cirrhosis, congestive heart failure, nephrotic syndrome, brain edema, cerebral ischemia, cerebral hemorrhage-stroke, thrombosis-bleeding and abnormal states of water rentention.

Peptide vasopressin antagonists suffer from a lack of oral activity and many of these peptides are not selective antagonists since they also exhibit partial agonist activity.

Premature birth can cause infant health problems and mortality and a key mediator in the mechanism of labor is the peptide hormone oxytocin. On the basis of the pharmacological action of oxytocin, antagonists of this hormone are useful in the prevention of preterm labor, B. E. Evans et al., J. Med. Chem. 35, 3919 (1992), J. Med. Chem., 36, 3993 (1993) and references therein. The compounds of this invention are antagonists of the peptide hormone oxytocin and are useful in the control of premature birth.

The present invention relates to novel tricyclic derivatives which exhibit antagonist activity at V₁ and/or V₂ receptors and exhibit in vivo vasopressin antagonist activity. The compounds also exhibit antagonist activity at oxytocin receptors.

Compounds of this invention may be prepared as shown in Scheme I by reaction of tricyclic derivatives of Formula 3a and 3b with a substituted or unsubstituted 4-nitrobenzoyl chloride 4 to give the intermediates 5a and 5b. Reduction of the nitro group in intermediates 5a and 5b gives the 4-aminobenzoyl derivatives 6a and 6b. The reduction of the nitro group in intermediates 5a and 5b may be carried out under catalytic reduction conditions (hydrogen-Pd/C; Pd/C- hydrazine-ethanol) or under chemical reduction conditions (SnCl₂ -ethanol; Zn-acetic acid; TiCl₃) and related reduction conditions known in the art for converting a nitro group to an amino group. The conditions for conversion of the nitro group to the amino group are chosen on the basis of compatibility with the preservation of other functional groups in the molecule.

Reaction of compounds of Formula 6a and 6b with aroyl chloride or related activated aryl carboxylic acids in solvents such as chloroform, dichloromethane, dioxane, tetrahydrofuran, toluene and the like in the presence of a tertiary base such as triethylamine and diisopropylethylamine or pyridine and the like, affords the compounds 8a and 8b which are vasopressin antagonists. ##STR39##

Reaction of tricyclic derivatives of Formula 6a and 6b with either a carbamoyl derivative 9 or a isocyanate derivative 10 gives compounds (Scheme 2) of Formula 11a and 11b which are vasopressin antagonists of Formula I wherein R₆ is ##STR40## and R_(b) is H, CH₃ or C₂ H₅. ##STR41##

Reaction of tricyclic derivatives of Formula 6a and 6b with arylacetic acids, activated as the acid chlorides 12, anhydrides, mixed anhydrides or activated with known activating reagents, gives compounds 13a and 13b (Scheme 3). ##STR42##

The compounds of Formula I wherein Y, A--B, Z, R₁, R₂ and R₃ are as defined and the aryl of R₃ (--COAr) is ##STR43## may be prepared, as shown in Scheme 4, by reacting an activated ester of the indole-5-carboxylic acids 14 with tricyclic derivatives 3a and 3b. The indole-5-carboxylic acids 14 may be activated by preparing the anhydride, a mixed anhydride or reacting with diethyl cyanophosphonate, N,N-carbonyldiimidazole or related peptide coupling reagents. As an example, the derivative 15 may be prepared by the reaction of acid 14 and N,N-carbonyldiimidazole in tetrahydrofuran; the solvent is removed and the derivative reacted with 3a or 3b at 100° C. to 120° C. without a solvent. Alternatively, 3a and 3b may be reacted with 15 in a solvent such as toluene or xylene at reflux temperatures. The activating reagent for the indole acids 14 is chosen on the basis of its compatibility with the R₄ group and its reactivity with the tricyclic derivatives 3a and 3b to give the vasopressin antagonists 16a and 16b. ##STR44##

The compounds of Formula I wherein Y, A--B, Z, R₁, R₂ and R₃ are as defined and the R₃ (--COAr) aryl group is ##STR45## wherein R₆ is ##STR46## may be prepared as shown in Scheme 5 by first reacting the derivatives 8a and 8b with sodium hydride or similar reagents to form the amide anion and then reacting the anion with a dialkoxyphosphoryl chloride to give the intermediates 17a and 17b. Reaction of these intermediates with sodium or lithium azide gives the products 18a and 18b. ##STR47##

Alternatively, the products 18a and 18b may be prepared by coupling tetrazole derivatives of the Formula 19 with tricyclic derivatives 3a and 3b (Scheme 6). The tetrazole carboxylic acids are activated for coupling to the tricyclic compounds 3a and 3b by reaction with peptide coupling reagents, by conversion to the acid chlorides, anhydrides or mixed anhydrides. ##STR48##

As an alternative method for synthesis of compounds of this invention as depicted in Formula I wherein Y, A--B, R₁, R₂, and Z are as previously defined and R₃ is ##STR49## is the coupling of aryl carboxylic acids 20a with the tricyclic derivatives 3a and 3b as shown in Scheme 7.

The aryl carboxylic acids are activated for coupling by conversion to an acid chloride, bromide or anhydride or by first reacting with an activating reagent such as N,N-dicyclocarbodiimide, diethyl cyanophosphonate and related "peptide type" activating reagents. The method of activating the acids 20a for coupling to the tricyclic derivatives 3a and 3b is chosen on the basis of compatibility with other substituent groups in the molecule. The method of choice is the conversion of the aryl carboxylic acids 20a to the corresponding aroyl chloride. The aryl acid chlorides 20 may be prepared by standard procedures known in the art, such as reaction with thionyl chloride, oxalyl chloride and the like. The coupling reaction is carried out in solvents such as halogenated hydrocarbons, toluene, xylene, tetrahydrofuran dioxane in the presence of pyridine or tertiary bases such as triethylamine and the like. Alternatively, the aroyl chlorides, prepared from the aryl carboxylic acids 20, may be reacted with derivatives 3a and 3b in pyridine with or without 4-(dimethylamino)pyridine to give derivatives 21a and 21b.

In general, when the aryl carboxylic acids are activated with N,N-carbonyldiimidazole and other "peptide type" activating reagents, higher temperatures are required than when the aroyl chlorides are used. The reaction may be carried out in a higher boiling solvent xylene or without a solvent (100° C. to 150° C.). ##STR50##

The starting materials 3a and 3b in Scheme 1 can be made by literature methods. For example, intermediate 6,11-dihydro-5H-dibenz b,e!azepines and substituted derivatives are prepared according to literature procedures: L. H. Werner, et al., J. Med. Chem., 8, 74-80 (1965); A. W. H. Wardrop et al., J. Chem. Soc. Perkins Trans I, 1279-1285 (1976).

Substituted 5,11-dihydrodibenz b,e!azepin-6-one are prepared by literature procedures: J. Schmutz et al., Helv. Chim. Acta., 48, 336 (1965); and reduced to substituted 6,11-dihydro-5H-dibenz b,e!azepines with lithium aluminum hydride, diborane, diborane-dimethylsulfide and agents known to reduce an amide carbonyl to a methylene group. Intermediate 10,11-dihydrodibenz b,f! 1,4!thiazepines are prepared by literature procedures--for example, see K. Brewster et al., J. Chem. Soc. Perkin I, 1286 (1976). Reduction of either dibenz b,f! 1,4!oxazepines A. W. H. Wardrop et al., J. Chem. Soc. Perkin Trans. I, 1279 (1976)! and dibenz b,f! 1,4!oxazepin-11(10H)-ones and dibenz b,f! 1,4!thiazepin-11(10H)-ones--J. Schmutz et al., Helv. Chim. Acta, 48, 336 (1965); may be carried out with lithium aluminum hydride in inert solvents such as dioxane and the like. The tricyclic 6,7-dihydro-5H-dibenz b,d!azepine intermediates of Formula 30 may be prepared by the literature procedures: T. Ohta et al., Tetrahedron Lett., 26, 5811 (1985); Wiesner et al., J. Amer. Chem. Soc., 77, 675 (1955); or derivatives may be prepared by coupling procedures illustrated in Scheme 8. The reduction of nitro compounds of structure type 31 followed by ring closure, affords lactams 32 which are reduced to give tricyclic azepines of Formula 33.

5,11-Dihydro-6H-pyrido 3,2-c! 1!benzazepines are prepared by literature procedures--J. Firl et. al., Liebigs Ann. Chem. 469, (1989). Tricyclic 1,2,3,4-tetrahydropyrazolo 4,3-c! 1!benzazepines are synthesized as described in the literature--G. Palazpino et. al., J. Heterocyclic Chem., 26, 71 (1989). ##STR51##

Tricyclic intermediates 42 for the synthesis of selected vasopressin antagonists of this invention wherein Y in Formula I is --CH₂ -- and m is one, may be prepared as shown in Scheme 9. Suitable 1-nitro-2-chloro or 1-nitro-2-bromo heterocycles 35 undergo halogen exchange when reacted with an alkyllithium reagent such as t-butyllithium, s-butyllithium or n-butyllithium to give intermediates 37 which react with anhydrides of Formula 38. R₁₂ is tert-butyl, secondary butyl, n-butyl, 2,6-dimethylpiperidine or a hindered non-nucleophilic dialkylamine. The nitro products 39 are reduced with hydrogen and a suitable catalyst or chemically reduced (Zn-acetic acid, TiCl₃ etc.) to the amino intermediates 40. Ring closure to the cyclic lactams 41 is conveniently carried out by heating in xylene or an inert solvent at 100° C. to 200° C. The cyclic lactams of structure type 41 are readily reduced by diborane in tetrahydrofuran, diborane-dimethylsulfide in tetrahydrofuran or lithium aluminum hydride in a suitable solvent such as dioxane to give the tricyclic compounds 42. ##STR52##

Alternatively, as shown in Scheme 10, some of the tricyclic derivatives of structural type 42 may be prepared by "palladium" type coupling or "copper" induced coupling of halogenated derivatives 43 to give tricyclic lactams 44. Reduction of the lactam carbonyl group gives the intermediates 42. Coupling of halogen derivatives 45 to effect ring closure with activated copper or "palladium" type reagents which induce aryl coupling gives lactams 46. Diborane reduction of lactams 46 gives derivatives 47.

Tetrahydro-1H-1-benzazepin-5-ones 51 and the tetrahydro-1H-1-benzazepin-2,5-diones 52 are useful compounds for the synthesis of intermediate tricyclic heterocyclic structures 53 and 54 (Scheme 11). The tetrahydrobenzazepin-5-ones 51 and 52 may be formylated to give hydroxymethylene derivatives or reacted with either the Vilsmeier reagent or the N,N-dimethylformamide dimethyl acetal to give the dimethylaminomethylene derivatives. The construction of heterocyclic rings from α-hydroxymethyleneketones by reactions with hydrazine N-methylhydrazine, hydroxylamine or formamidine to give pyrazoles, N-methylpyrazoles, oxazoles or pyrimidines respectively, is a standard literature procedure. See Vilsmeier formylation--Tetrahedron, 49, 4015-4034 (1993) and references therein and ring formations--J. Heterocyclic Chem., 29, 1214 (1992) and references therein.

Soc. 456 (1937); Tetrahedron 49, 1807 (1993)! (Schmidt reaction). Reduction of tetrahydro-1H-benzazepin-2-ones gives the tetrahydro-1H-benzazepines 48 which on acylation gives compounds 49. Oxidation of N-acyl tetrahydro-1H-benzapines of type 49 to give the 5-one derivatives is a known oxidative procedure; R. L. Augustine and W. G. Pierson, J. Org. Chem., 34, 1070 (1969).

Binding Assay to Rat Hepatic V₁ Receptors

Rat liver plasma membranes expressing the vasopressin V₁ receptor subtypes are isolated by sucrose density gradient according to the method described by Lesko et al., (1973). These membranes are quickly suspended in 50.0 mM Tris.HCl buffer, pH 7.4, containing 0.2% bovine serum albumin (BSA) and 0.1 mM phenylmethylsulfonylfluoride (PMSF) and kept frozen at -70° C. until used in subsequent binding experiments. For binding experiments, the following is added to the wells of a ninety-six well format microtiter plate: 100 μl of 100.0 mM Tris.HCl buffer containing 10.0 mM MgCl₂, 0.2% heat inactivated BSA and a mixture of protease inhibitors: leupeptin, 1.0 mg %; aprotinin, 1.0 mg %; 1,10-phenanthroline, 2.0 mg %; trypsin inhibitor, 10.0 mg % and 0.1 mM PMSF, 20.0 μl of phenyl-alanyl-3,4,5,-³ H! vasopressin (S. A. 45.1 Ci/mmole) at 0.8 nM, and the reaction initiated by the addition of 80 μl of tissue membranes containing 20 μg of tissue protein. The plates are kept undisturbed on the bench top at room temperature for 120 min. to reach equilibrium. Non-specific samples are assayed in the presence of 0.1 μM of the unlabeled antagonist phenyl-alanylvasopressin, added in 20.0 μl volume.

For test compounds, these are solubilized in 50% dimethylsulfoxide (DMSO) and added in 20.0 μl volume to a final incubation volume of 200 μl . Upon completion of binding, the content of each well is filtered off, using a Brandel® cell Harvester (Gaithersburg, Md.). The radioactivity trapped on the filter disk by the ligand-receptor complex is assessed by liquid scintillation counting in a Packard LS Counter, with an efficiency of 65% for tritium. The data are analyzed for IC₅₀ values by the LUNDON-2 program for competition (LUNDON SOFTWARE, OH) and displayed in Table I.

Binding Assay to Rat Kidney Medullary V₂ Receptors

Medullary tissues from rat kidneys are dissected out, cut into small pieces and soaked in a 0.154 mM sodium chloride solution containing 1.0 mM EDTA with many changes of the liquid phase, until the solution is clear of blood. The tissue is homogenized in a 0.25M sucrose solution containing 1.0 mM EDTA and 0.1 mM PMSF using a Potter-Elvehjem homogenizer with a teflon pestle. The homogenate is filtered through several layers (4 layers) of cheese cloth. The filtrate is rehomogenized using a dounce homogenizer, with a tight fitting pestle. The final homogenate is centrifuged at 1500×g for 15 min. The nuclear pellet is discarded and the supernatant fluid recentrifuged at 40,000×g for 30 min. The resulting pellet formed contains a dark inner part with the exterior, slightly pink. The pink outer part is suspended in a small amount of 50.0 mM Tris.HCl buffer, pH 7.4. The protein content is determined by the Lowry's method (Lowry et al., J. Biol. Chem., 1953). The membrane suspension is stored at -70° C., in 50.0 mM Tris. HCl, containing 0.2% inactivated BSA and 0.1 mM PMSF in aliquots of 1.0 ml containing 10.0 mg protein per ml of suspension until use in subsequent binding experiments.

For binding experiments, the following is added in μl volume to wells of a 96 well format of a microtiter plate: 100.0 μl of 100.0 mM Tris.HCl buffer containing 0.2% heat inactivated BSA, 10.0 mM MgCl₂ and a mixture of protease inhibitors: leupeptin, 1.0 mg %; aprotinin, 1.0 mg %; 1,10-phenanthroline, 2.0 mg %; trypsin inhibitor, 10.0 mg % and 0.1 mM PMSF, 20.0 μl of ³ H! Arginine⁸, vasopressin (S. A. 75.0 Ci/mmole) at 0.8 nM and the reaction initiated by the addition of 80.0 μl of tissue membranes (200.0 μg tissue protein). The plates are left undisturbed on the bench top for 120 min to reach equilibrium. Non-specific binding is assessed in the presence of 1.0 μM of unlabeled ligand, added in 20 μl volume. For test compounds, these are solubilized in 50% dimethylsulfoxide (DMSO) and added in 20.0 μl volume to a final incubation volume of 200 μl. Upon completion of binding, the content of each well is filtered off, using a Brandel® cell Harvester (Gaithersburg, Md.). The radioactivity trapped on the filter disk by the ligand-receptor complex is assessed by liquid scintillation counting in a Packard LS Counter, with an efficiency of 65% for tritium. The data are analyzed for IC₅₀ values by the LUNDON-2 program for competition (LUNDON SOFTWARE, OH) and displayed in Table I.

Radioligand Binding Experiments with Human Platelet Membranes

(a) Platelet Membrane Preparation:

Frozen platelet rich plasma (PRP), received from the Hudson Valley Blood Services, are thawed to room temperature. (Platelet Source: Hudson Valley Blood Services, Westchester Medical Center, Valhalla, N.Y.). The tubes containing the PRP are centrifuged at 16,000×g for 10 min. at 4° C. and the supernatant fluid discarded. The platelets resuspended in an equal volume of 50.0 mM Tris.HCl, pH 7.5 containing 120 mM NaCl and 20.0 mM EDTA. The suspension is recentrifuged at 16,000×g for 10 min. This washing step is repeated one more time. The wash discarded and the lysed pellets homogenized in low ionic strength buffer of Tris.HCl, 5.0 mM, pH 7.5 containing 5.0 mM EDTA. The homogenate is centrifuged at 39,000×g for 10 min. The resulting pellet is resuspended in Tris.HCl buffer, 70.0 mM, pH 7.5 and recentrifuged at 39,000×g for 10 min. The final pellet is resuspended in 50.0 mM Tris.HCl buffer pH 7.4 containing 120 mM NaCl and 5.0 mM KCl to give 1.0-2.0 mg protein per ml of suspension.

(b) Binding to Vasopressin V₁ receptor subtype in Human Platelet Membranes:

In wells of a 96 well format microtiter plate, add 100 μl of 50.0 mM Tris.HCl buffer containing 0.2% BSA and a mixture of protease inhibitors (aprotinin, leupeptin etc.). Then add 20 μl of ³ H!Ligand (Manning or Arg⁸ Vasopressin), to give final concentrations ranging from 0.01 to 10.0 nM. Initiate the binding by adding 80.0 μl of platelet suspension (approx. 100 μg protein). Mix all reagents by pipetting the mixture up and down a few times. Non specific binding is measured in the presence of 1.0 μM of unlabeled ligand (Manning or Arg⁸ Vasopressin). Let the mixture stand undisturbed at room temperature for ninety (90) min. Upon this time, rapidly filter off the incubate under vacuum suction over GF/B filters, using a Brandel Harvester. The radioactivity caught on the filter disks is determined by the addition of liquid scintillant and counting in a liquid scintillator.

Binding to Membranes Of Mouse Fibroblast Cell Line (LV-2) Transfected with the cDNA Expressing the Human V₂ Vasopressin Receptor

(a) Membrane Preparation

Flasks of 175 ml capacity, containing attached cells grown to confluence, are cleared of culture medium by aspiration. The flasks containing the attached cells are rinsed with 2×5 ml of phosphate buffered saline (PBS) and the liquid aspirated off each time. Finally, 5 ml of an enzyme free dissociation Hank's based solution (Specialty Media, Inc., Lafayette, N.J.) is added and the flasks are left undisturbed for 2 min. The content of all flasks is poured into a centrifuge tube and the cells pelleted at 300×g for 15 min. The Hank's based solution is aspirated off and the cells homogenized with a polytron at setting #6 for 10 sec in 10.0 mM Tris.HCl buffer, pH 7.4 containing 0.25M sucrose and 1.0 mM EDTA. The homogenate is centrifuged at 1500×g for 10 min to remove ghost membranes. The supernatant fluid is centrifuged at 100,000×g for 60 min to pellet the receptor protein. Upon completion, the pellet is resuspended in a small volume of 50.0 mM Tris.HCl buffer, pH 7.4. The protein content is determined by the Lowry method and the receptor membranes are suspended in 50.0 mM Tris.HCl buffer containing 0.1 mM phenylmethylsulfonylfluoride (PMSF) and 0.2% bovine serum albumin (BSA) to give 2.5 mg receptor protein per ml of suspension.

Conscious hydrated rats are treated with compounds under study from 0.1 to 100 mg/kg orally or vehicle. Two to four rats are used for each compound. One hour later, arginine vasopressin (AVP, antidiuretic hormone, ADH) dissolved in peanut oil is administered at 0.4 μg/kg intraperitoneally. Two rats in each test would not receive arginine vasopressin but only the vehicle (peanut oil) to serve as water-loading control. Twenty minutes later each rat is given 30 mL/kg of deionized water orally by gavage and is placed individually in a metabolic cage equipped with a funnel and a graduated glass cylinder to collect urine for four hours. Urine volume is measured and osmolality analyzed by use of a Fiske One-Ten osmometer (Fiske Assoc., Norwood, Mass., USA). Urinary sodium, potassium, and chloride are analyzed by use of ion-specific electrodes in a Beckman E3 (Electrolyte 3) Analyzer. In the following results, decreased urine volume and decreased osmolality relative to AVP-control indicates activity. The results are displayed in Table II.

Vasopressin V₁ Antagonist Activity in Conscious Rats

Conscious rats are restrained in a supine position with elastic tape. The area at the base of the tail is locally anesthetized by subcutaneous infiltration with 2% procaine (0.2 ml). Using aseptic technique the ventral caudal tail artery is isolated and a cannula made of PE 10 and 20 (heat-fused) tubing is passed into the lower abdominal aorta. The cannula is secured, heparinized (1000 i.u./cc), sealed and the wound closed with one or two stitches of Dexon 4-0. The caudal vein is also cannulated in the same manner for intravenous drug administration. The duration of the surgery is approximately 5 minutes. Additional local anesthesia (2% procaine or lidocaine) is provided as needed.

The animals are placed in plastic restraining cages in an upright position. The cannula is attached to a Statham P23Db pressure transducer and pulsatile blood pressure is recorded. Increase of systolic blood pressure responses to arginine vasopressin 0.01 and 0.2 international unit (I.U.)(350 I.U.=1 mg) injections are recorded prior to any drug (compound) administration, after which each rat is dosed orally with compounds under study 0.1-100 mg/kg (10 cc/kg) or intravenously 0.1-30 mg/kg (1 cc/kg). The vasopressin injections are repeated 30,60,90,120,180,240 and 300 min. later. Percentage of antagonism by the compound is calculated using the pre-drug vasopressin vasopressor response as 100%.

The results of this test on representative compounds of this invention are shown in Table III.

Oxytocin Receptor Binding

(a) Membrane Preparation

Female Sprague-Dawley rats weighing approximately 200-250 g are injected intramuscularly (i.m.) with 0.3 mg/kg of body weight of diethylstilbestrol (DES). The rats are sacrificed 18 hours later under pentobarbital anesthesia. The uteri are dissected out, cleaned of fat and connective tissues and rinsed in 50 ml of normal saline. The tissue pooled from six rats is homogenized in 50 ml of 0.01 mM Tris.HCl, containing 0.5 mM dithiothreitol and 1.0 mM EDTA, adjusted to pH 7.4, using a polytron at setting 6 with three passes of 10 sec each. The homogenate is passed through two (2) layers of cheesecloth and the filtrate centrifuged at 1000×g for 10 min. The clear supernatant is removed and recentrifuged at 165,000×g for 30 min. The resulting pellet containing the oxytocin receptors is resuspended in 50.0 mM Tris. HCl containing 5.0 mM MgCl₂ at pH 7.4, to give a protein concentration of 2.5 mg/ml of tissue suspension. This preparation is used in subsequent binding assays with ³ H!Oxytocin.

(b) Radioligand Binding

Binding of 3,5- ³ H!Oxytocin ( ³ H!OT) to its receptors is done in microtiter plates using ³ H!OT, at various concentrations, in an assay buffer of 50.0 mM Tris. HCl, pH 7.4 and containing 5.0 mM MgCl₂, and a mixture of protease inhibitors: BSA, 0.1 mg; aprotinin, 1.0 mg; 1,10-phenanthroline, 2.0 mg; trypsin, 10.0 mg; and PMSF, 0.3 mg per 100 ml of buffer solution. Non-specific binding is determined in the presence of 1.0 uM unlabeled OT. The binding reaction is terminated after 60 min., at 22° C., by rapid filtration through glass fiber filters using a Brandel® cell harvester (Biomedical Research and Development Laboratories, Inc., Gaithersburg, Md.). Competition experiments are conducted at equilibrium using 1.0 nM ³ H!OT and varying the concentration of the displacing agents. The concentrations of agent displacing 50% of ³ H!OT at its sites (IC₅₀) are calculated by a computer assisted LUNDON-2 program (LUNDON SOFTWARE INC., Ohio, USA).

The compounds of the present invention can be used in the form of salts derived from pharmaceutically or physiologically acceptable acids or bases. These salts include, but are not limited to, the following: salts with inorganic acids such as hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid and, as the case may be, such organic acids as acetic acid, oxalic acid, succinic acid, and maleic acid. Other salts include salts with alkali metals or alkaline earth metals, such as sodium, potassium, calcium or magnesium or with organic bases. The compounds can also be used in the form of esters, carbamates and other conventional "pro-drug" forms, which, when administered in such form, convert to the active moiety in vivo. When the compounds are employed for the above utility, they may be combined with one or more pharmaceutically acceptable carriers, for example, solvents, diluents and the like, and may be administered orally in such forms as tablets, capsules, dispersible powders, granules, or suspensions containing, for example, from about 0.05 to 5% of suspending agent, syrups containing, for example, from about 10 to 50% of sugar, and elixirs containing, for example, from about 20 to 50% ethanol, and the like, or parenterally in the form of sterile injectable solution or suspension containing from about 0.05 to 5% suspending agent in an isotonic medium. Such pharmaceutical preparations may contain, for example, from about 0.05 up to about 90% of the active ingredient in combination with the carrier, more usually between about 5% and 60% by weight.

The effective dosage of active ingredient employed may vary depending on the particular compound employed, the mode of administration and the severity of the condition being treated. However, in general, satisfactory results are obtained when the compounds of the invention are administered at a daily dosage of from about 0.5 to about 500 mg/kg of animal body weight, preferably given in divided doses two to four times a day, or in a sustained release form. For most large mammals the total daily dosage is from about 1 to 100 mg, preferably from about 2 to 80 mg. Dosage forms suitable for internal use comprise from about 0.5 to 500 mg of the active compound in intimate admixture with a solid or liquid pharmaceutically acceptable carrier. This dosage regimen may be adjusted to provide the optimal therapeutic response. For example, several divided doses may be administered daily or the dose may be proportionally reduced as indicated by the exigencies of the therapeutic situation.

These active compounds may be administered orally as well as by intravenous, intramuscular, or subcutaneous routes. Solid carriers include starch, lactose, dicalcium phosphate, microcrystalline cellulose, sucrose and kaolin, while liquid carriers include sterile water, polyethylene glycols, non-ionic surfactants and edible oi8ls such as corn, peanut and sesame oils, as are appropriate to the nature of the active ingredient and the particular form of administration desired. Adjuvants customarily employed in the preparation of pharmaceutical compositions may be advantageously included, such as flavoring agents, coloring agents, preserving agents, and antioxidants, for example, vitamin E, ascorbic acid, BHT and BHA.

The preferred pharmaceutical compositions from the standpoint of ease of preparation and administration are solid compositions, particularly tablets and hard-filled or liquid-filled capsules. Oral administration of the compounds is preferred.

These active compounds may also be administered parenterally or intraperitoneally. Solutions or suspensions of these active compounds as a free base or pharmacologically acceptable salt can be prepared in water suitably mixed with a surfactant such as hydroxypropylcellulose. Dispersions can also be prepared in glycerol, liquid polyethylene glycols and mixtures thereof in oils. Under ordinary conditions of storage and use, these preparation contain a preservative to prevent the growth of microorganisms.

The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases, the form must be sterile and must be fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol(e.g., glycerol, propylene glycol and liquid polyethylene glycol), suitable mixtures thereof, and vegetable oils.
